I suppose if you send them to a wallet and put the wallet on a usb and write over it a couple thousand times it will unrecoverable
The last thing you want is getting accused of scam coin. If we send it to V1111111111111 or V2222222222 etc it is as good as burn, unless some expert want to suggest a better way. It takes trillions of years to decrypt something like this.
Hope this helps.
